Tempur-Adapt® Series Medium HybridMade from all-new combinations of our proprietary materials, the TEMPUR-Adapt® series adapts and responds to your body’s needs throughout the night. Continuously conforming. Relieving pressure. Reducing motion. Delivering just the right sleep for your body so you wake up feeling powerful.It’s not mechanical. It’s material. And it’s personal. A unique cell structure within our material is activated by the unique characteristics of your body. Your weight, your shape, your temperature, your sleep position. Even as these elements change throughout the night, our legendary material continues to comfort, support and conform to your body—unlike ordinary memory foams, which don’t continuously adapt or traditional spring mattresses, which simply push up on you wherever you push down on them. This is a difference you can feel allover. Not just tonight, but tomorrow too.Key HighlightsTempur-ES® : The tighter, slightly rougher cell structure of TEMPUR-ES® creates a softer feel that works in combination with other layers to support and relax.Original Tempur® : Originally formulated to absorb the G-Force of NASA astronauts travelling into space and then perfected by us for sleepers—it’s as comfortable and supportive as it is iconic.Cool-To-Touch Cover: Premium knit technology for superior cool-to-touch feel.
